LUBRICATOR.

To all whom t may concern: Y `e it known that l, WILLIAM JQ BEAGLE,

"of Syracuse, New York, in the county of Onondaga, in the y (invented new and useful Improvements in Lubricators, of which the following, taken State of New York, have in connection with the accompanying drawings, 1s a full, clear, and exact description.

This invention relates to certain improvements in lubricators of the class set forth in my pending application, Serial No. 353,273,

be lubricated, and containing a roller sprin pressed into contact with the second name part for rolling contact therewith to distribute the oil evenly over and upon the surface thereof.

shown" by dotted lines.

In the pending applicationreferred to, as

Vin the present application, the main object is to` enable the oil feeding tube with the roller "and spring therein to be adjusted axially forbringing the roller into rolling contact with one of the parts to be lubricated without detaching the oil containerfrom the part to which it is secured.`

One of the specific objects ofmy present invention is to make the tube-'adjusting means a part of the lubricating device, `or rather to incorporate it therein in such manner that it is always available for operation to adjust the tube without disturbing the container from its" operative position.u

Another object is to provide means for covering and concealing the tube-adjusting means when the tube has been properly adjusted. Other objects and uses will be brought out in the following-description.

` In'the drawings, Figure 1 is a longitudinal sectional view of a lubricating device 'embodying the various features of Inyinvention, the` parts to Fig. 2 shows `perspective views of the' detached'parts of theoil feeding tube and its ,a'djusting means. o

In order that my invention may be clearly Specification of-LettersPatent. 4Application filed November `6,1920.` `Serial No.

"with central lengthwise be` lubricated being -l5- being Patented oet. ii, iaei.

`understood I have shown relatively rotatable. parts A- and cured `upon the adjacent ends of a central connectingtube '-6- and are engaged with the'corresponding ends of the shell -3- to form the `oil chamber -,-7-.

y The heads *t-f and -5- are provided openings -8 and 49% therethrough for the exit and entrance of oil and for other purposes hereinafter described, the walls of said openings being threaded Vfor receiving the externally threaded adjacent ends of the connecting-,tube -6-. Thenner end of the inner opening `8- is reduced in diameter but is threaded to receive an externally threaded oil feedingtube -10*, which is adjustable endwise or axially by rotation toward and from the bearing between the relatively rotatable part-s *A4 and -B-.

A ball or roller -11- is seated in the inner end of the oil feeding-tube -l0 for rolling contact with the periphery of the part A- and is yieldingly held in en* gagement with said part by means of a coil spring -`-l2- within the tube l0- A relatively smaller ball -13- is interposed between the contact ball -lland the adjacent end 'ofthe spring 12- to reduce friction and thereby permit the ball *ll-- to be rotated more freely by contact with the part -A-, as the parts -A- and .-B-- are relatively rotated, thereby effecting an even distribution of the oil over and upon the bearing between those parts without waste.

The oil feeding-tube -10- is preferably composed of an inner section -14, an outer section l5- and an intermediate section -16-, the sections `l2#- and preferably made of thin, steel tubing and are arranged coaxially in spaced Vprojecting pin or stud relation end to end and connected by the intermediate tube -l6-, which is preferably made ot brass tubing and is threaded externally to engage the reduced threaded part of the opening -8-, said intermediate section -16- being permanently secured by a tight fit to the section -l4land is also secured by a cotter key or pin -17- to the inner end ot the section -15-, whereby the rotation of the outer section -15- will impart similar turning movement to the sections iM and -16- for adjusting the tube -10- axially to bring the ball or roller -lleto proper contact with the periphery of the part -A- for rolling movement, it being understood that the section -14- extends inwardly some distance beyond the inner end of the nipple -2-, when the lubricator is adjusted for use. The tube lO- as a whole, is held in its adjusted position by a clamping block -18- and a set screw -l9-, both of which are movable in a radial opening in the nipple -2-, as shown in Fig. l, the inner end of the clamping block 8 being serrated to engage the thread of the intermediate section -l6 and thereby to prevent mutilation of the threads.

An externally threaded tubular bushing ---20-- is screwed in the outer end of the section -t4- for adjusting the tension of the spring -l2 upon the ball -11-, said spring serving to hold the ball in contact with the periphery of the part -A-.

The connecting-tube 6 communicates with the oil chamber --7-- through radial passages 2lto allow the oil to i'low from said chamber to the interior of the tube and, thence, through one or more openings -22- into the interior of the feeding-tube -10-, through which it flows to the bearing between the parts -A- and B-.

The outer section -15- of the oil feeding-tube extends through the major portion ot the connecting-tube -6- or to a point within a relatively short distance of the outer head -5--, and is provided with a lengthwise slot -23- in one side for cooperation with a suitable turning member 24-, which extends some distance into the outer end or" the section -157-, and is provided near its inner end with a radially Y V25 projecting into the slot 23-- 'for turning the tube -lO-, as member -2-- is rotated.

The outer threaded end oi' the connectingtube -6- extends through and beyond the outer end head -5- and is engaged by a screw cap 2G-- which constitutes a closure for the adjacent open endet the tube and also for 'the opening -9-.

The outer end of the member Q4- is enlarged and provided with a knurled hea-d -27- resting upon the outer end of the connecting tube -6- to hold it against inward axial movement and to permit it to be always accessible for engagement by hand in turning the feeding-tube --l(lto properly adjust the ball 1lagainst the peripherj7 of the part -A-, when the oil cup is adjusted 'tor use and the cap QG- removed.

That is, by extending the head -27- of the adjustingr member 24.- outwardly beiond the head 5 and connecting-tube -G-, enables the feeding-tube -l0-- with the ball l1- and spring -12- therein to be adjusted to a nicety after the lubricator is installed and without displacing any of its parts other than the loosening of' the set screw --19-- and removal oi the ca i -Z6, both of which are accessible at all times. After the adjustment is made. the set screw -19- may be tightened and the cap Q6- replaced to cover the outer end of the adjusting member Q4- and opening -9-, the entire device being then ready ttor use.

Vhat I claim is:

1. A lubricator comprisingr an oil-container having inner and outer end heads provided with coaxial openings therethrough, the inner head having means for securement to one ot the parts to be lubricated, a tube movable endwise in the inner opening tor feeding oil from said container to another part to be lubricated, a roller in the inner end of said tube tor rolling contact with the second named part. a spring for yieldingly holding the roller in contact with said second named part` means extending through the outer opening for adjusting said tube endwise, and a movable closure for the outer opening normally covering the outer end ot the tube-adjusting means.

2. A lubricator comprising an oil-container having inner and outer end heads provided with coaxial openings therethrough, the inner head having means Vfor securement to one ot the parts to be lubricated, a tube having screw engagement with the walls of' the inner opening for endwise adjustment by turning, a ball in the inner end of the tube spring pressed toward the other part to be lubricated. a rotary incinber in the outer opening, means for transmitting rotary motion trom said member to the tube, and means for holding said member against inward movement. when rotated to adjust the tube.

3. ln a lubricator oi the character described, the combination ot a container having its inner and outer end hiads provided with openings therethrough, the inner head having means for attachmentl to one of' the parts to be lubricated, a tubular member extending into said openings and connecting said heads, an oil 'feeding-tube adjustable endwise in the inner opening and extending to a point in proximity to the bearing to be lubricated, said oil feedingtube also extending outwardly into the tube which connects the heads, means movable n the outer end of the head-connecting tube and engaged with the outer end of the oil-feed ing-tube for adjusting the latter axially, and a screw cap engagbng the outer end of the head-connecting tu e and normally covering the outer end of the adjusting means for the oil-feeding-tube.

In Witness whereof I have hereunto set my hand this 26 day of October, 1920.
